IMPROVEMENT IN AXLE-LUBRICATORS.

Specication forming part of Letters Patent No. 117,581, dated August l, 1871.

To all whom it may concern:

Be it known that I, HENRY S. WEAVER, of Irwin Station, in the county of Vestmoreland and State of Pennsylvania, have invented a new and useful Improvement in Axle-Lubricator 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others`skilled in the art to make an d use the same, reference being had to the accompanying drawing forming part of this speciiication.

This invention relates to a new and useful improvement in a device for lubricating the axles or journals of loose wheels, designed more especially for wheeled vehicles, as wagons, carriages, dre., but applicable to other purposes 5' and it consists in a box or oil-reservoir placed between the spokes or in connection with the hub of the wheel, so that the oil will pass from the reservoir to the axle or journal, in the manner hereinafter described.

In the accompanying drawing, Figure 1 represents a vertical section ofthe lubricator taken on the line :c a; of Fig. 2, showing it applied to a wagon-wheel. Fig. 2 is a top view oi the reservoir with the cover off'.

Similar letters of reference indicate corresponding parts.

A is the box or reservoir. B is the tube extendving from the bottom ofthe reservoir to near its top. C is a diaphragm, with a collar which iits tightly onto the tube B with a small hole through to correspond in position with the center of the tube. The diaphragm or plate C is made to rit the sides of the reservoir 5 but an opening is left at one or both ends. The plate or diaphragm is made a little concave so that oil upon it will run toward the central hole and find its way into the tube and down through a hole in the hub, as seen in Fig. 1. Oil is introduced into the reservoir through the orice D, which oriice is closed by a screw-plug, E, as seen in Fig. 2. F is the top ofthe reservoir, which is tightly packed and fitted on, as seen in Fig. l. l

When the wheel revolves some of the oil will lodge on the plate and run down the tube to the axle, which will be sufficient for` its proper lubrication. The lu'bricator is attached so that it is readily removed for cleaning or other purposes. By this arrangement the axle or shaft will be likely to receive a little oil at each revolution of the wheel.

The advantages of this device will be readily understood by any one acquainted with the subject.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In axle-lubricators, the diaphragm C, coneaved on top and centrally perforated, when combined as described with the oil-tube B that rises above the oil in reservoir A, so that at each revolution of the wheel a small portion of oil will be thrown upon the concavity or' the diaphragm and transferred by gravity through the tube to the axle.

HENRY S. WEAVER.
